Opis:
Stabilized He-Ne lasers are commonly utilized in interferometric systems, and provide easy and accurate results. The main reason for their extensive use is their output beam's strength and stability. However, these are relatively high in cost. In interferometric measurement systems, standard He-Ne lasers can also be used. This type of lasers has a lower cost, but their output beam strength can fluctuate in time. And this in turn adversely affects the measurement performance. In this study, a standard He-Ne and a stabilized He-Ne lasers were used in the same measurement system. The measurement errors caused by the fluctuation of the output beam of the standard He-Ne laser are minimized by using a video processing technique. When the obtained results were compared with the ideal values, the relative error for the system with the stabilized He-Ne laser was recorded as 0.2%, while for the system with the standard He-Ne laser a relative error rate of 0.3% was achieved. When the results are analyzed, it is evident that in measurement systems with a standard He-Ne laser, the system performance can be boosted with a video processing technique, and that its results can achieve values closer to the performance of stabilized He-Ne lasers.

Opis:
Interferometric measuring systems are frequently used in determining the precise changes. The light of the venture property is used in this system which is possible to perform measurements in the nanometer precision. Analysis of data, which are taken from interferometric measurement systems, can be performed by fringe counting, image processing. There are disadvantages of such kinds of methods which are cost, time and design challenge. The most innovation in our study, the need of electronic circuit or image processing algorithm for determining obtained values which are taken from measurement system as a result of processing part can be eliminated. In processing step, arrangement of the data is quite important in terms of the achieved results. Through data processing, it is provided to make faster analysis by the aid of increasing quantity of the data. The displacement values which are taken by data processing show 90% success when comparing them with both electronic and image processing techniques.

Opis:
In this study, investigation of video processing method which is a new technique for precision displacement measurement is presented. The video processing method was integrated with an interferometric system and the thermal expansion results and linear thermal expansion coefficients of a heated sample metals were compared with theoretical results. Michelson interferometer setup was used in our study due to its advantages in precision displacement information of a visual output, called interferograms. In the experimental studies, signals of interferograms containing displacement information were obtained from the measurement system. The amount of displacement in the sample metals under the temperature variation due to thermal expansion was measured with the analysis program, written in Matlab/Simulink environment, with a micrometer precision. The measured displacement amounts were compared with the results of theoretical calculations. According to the theoretical values, the relative error of the values measured with video processing based method, was found found to be 0.3%

Opis:
In this study, real time measurement of the linear expansion of industrial material undergoing temperature change by using a computer-aided interferometric measuring technique with micrometer accuracy is attempted. Aluminum and copper were subjected to temperature change in the thermal expansion experiment unit (LETI-1) causing them to expand linearly. The fringe number in the interference symbol, which includes the information about linear expansion and temperature change were transferred to a computer via a data acquisition card, graphed by a program created in the LabVIEW environment, and the amount of linear expansion was detected in real time.
